You clearly want to get better because you wouldn't have posted if you didn't. That was a brave first step.
Depression is like any other illness, it can be severe, mild or anywhere in between. You don't have to be suicidal. I have not been suicidal despite suffering from crippling depression at times. The trouble is, the illness distorts everything.
There are lots of support threads on the mental health section of this site and i think there was a thread about battling depression without medication if you are really against it.
Certain types of anti-depressants are addictive but they are generally not used now. The ADs used now are not addictive, although you can't stop them suddenly, its not addiction and stopping them over a couple of months is fine. There are often side effects when you first start taking them, they can range from feeling a bit nauseous to fucking horrendous, some people have to try a few different meds before they find what works for them. But most people don't struggle too much and they tend to go after a week or two.
The majority of people put onto ADs are on them for about six months so its not always a long term thing - like you say, you are not suicidal, so thats good, it might just put you in a place where you can think more clearly and find strategies to cope with whatever it is that is causing your issues.
Keep talking to us OP, so many of us have been in similar situations. It isn't hopeless
